Dual-Sided Displays: Where 1 + 1 ≠ 2

By Hank M Liu, AUO

Moving digital signage out from walls is an effective way to meeting messaging objectives in big, busy environments, but doing that presents an aesthetics problem. The screens look gorgeous, but the backs are also visible, and they don’t look anywhere near as nice.

They tend to be big swatches of dark metal, perforated for air flow and filled with connector slots for various cables.

The most obvious solution: cover them with more metal. But that tends to look boring and wastes prime visual real estate that could and should be used for in-store promotions or information displays.

Another, often-used tactic – install two screens back-to-back. That’s definitely a better approach, but not ideal. Viewers will still see the not-so-nice-looking frames and wires from a side view, but also, combining two screens makes for a bulky visual footprint. It also adds a lot of weight, which could add to capital costs on the installation, if the mounting surface needs to be reinforced.

There is a perfect solution, though: displays that come out of the factory as two-sided.

dual_1A dual-sided display is a large-format LCD screen that has matching display surfaces back to back. This is more than simply combining two screens. Instead, these dual-sided displays are designed and built from the ground up with integrated backlights that support both sides of the display.

What that means, in practical terms, is a product with a ridiculously slim profile. At just 23.4mm thick, a 55-inch, 700-nit dual-sided display manufactured by AUO and offered by ComQi is dramatically thinner than two conventional back-to-back LCDs.

These dual-sided displays work extremely well for a variety of use-cases. For a window display, the dual-sided screen can incentivize customers to come in on one “face” of the display, while on the reverse face thanking shoppers for visiting, as they leave the store.dual_2

Used as a floor fixture, these back-to-screens don’t take up much more space than a typical floor poster, but have immensely greater marketing power through vibrant, full-motion visuals and scheduling that can change messages every few seconds, instead of every few weeks.

For a ceiling mounted unit, the lighter dual-sided unit is a much better solution both in terms of its aesthetics and the minimal weight load.
